The fact of leaving the c1 note in bar 166 is a patent error at the time of implementing the authentic correction of FE1 (→EE). As a result, in the main text we give the corrected by Chopin version of analogous bars 13-14, 61-62 and 117-118. The versions of both GE1 and GE2 (→GE3GE4) are a result of revisions unifying analogous bars – bar 165 was assimilated to bar 13 and bar 166 to bar 14.

Like in previous occurrences of this bar A (→FEEE1) has no  raising g1 to g1 on the 4th L.H. quaver. The obvious oversight was corrected in GE and EE2.

FES includes a cautionary  next to c2 in the L.H. – most probably written with Chopin's hand.
